3-17 SOCKETS
3-17-1 SOCKETS Instances Configuration
A Sockets instance provides the data traffic at the IP addresses and ports level.
Basically, a sockets instance monitors a group of sockets (i.e. inet) matching one or several of following
characteristics:
• A local or a remote port
• A local host address
• A remote host or a remote network address
Two types of sockets are monitored: The TCP sockets and the UDP sockets. The sockets instance name syntax in
the USERCFG define the sockets type.
TCP sockets syntax:
sockets <ttp>./[<laddr>][:<lport>][/[<raddr>][:<rport>]] [,<trendFlag>]
UDP sockets syntax
sockets <ttp>.\:<lport> [,<trendFlag>]
Where,
• <ttp> is the TCP/IP transport process name. For example ‘$ztc0’.
‘/’ Sign identifies the socket using the TCP protocol (i.e. TCP socket type).
‘\’ Sign identifies the socket using the UDP protocol (i.e. UDP socket type).
• <laddr> is one of the local IP addresses managed by the transport process. If Omitted all IP addresses
managed by the transport process are considered.
• <lport> is a local port. (*)
• <raddr> is the IP address of a remote host or network.
• <rlport> is a remote listening port.
• <trendFlag> Is the flag trend=on or trend=off.
Example:
socket $ztc0./:23 == monitor all telnet connection.
socket $ztc0./:23/203.3 == monitor all telnet connection with remote hosts in
network 203.3
NOTE:
Sockets monitoring may require an adjustment of a DCPRM parameter ttpMaxNb and ttpSckMaxNb.
Refer
Appendix D: DCPRM File. After User adds Socket Instances to the USERCFG file the SV_DCPRM_SET
macro
needs to be executed to adjust ttpMaxNb and ttpSckMaxNb. Once executed OVNPM will need to be
stopped and restarted.
